This invention relates to mop wringers of the type having a fixedk and aswinging jaw with a lever connected to the latter in a manner to operateit; and it has for an 0bject to provide an improved construction whichwill be inexpensive to manufacture, more eective in operation, anddurable muse.

To these and other ends the invention consists in certain improvementsand combinations of parts all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings: Figure 1 is a perspective view of a mop wringerembodying my invention. Fig. 2 is a vertical section of the same on linea-a Fig. 3, and Fig. 3 a horizontal section on line b-Z) Fig. 2.

In the present embodiment of my invention I have shown a xed jawpreferably formed of sheet metal and having vertical ribs 1 providedwith longitudinal drain openings or slots 3, the ribs 1 being formed bystamping and acting to strengthen the jaw horizontally7 and a roll bead4 being formed along the upper edge to strengthen the aw vertically.

Secured to the side edges of the fixed jaw are side pieces 5 eachpreferably made of sheet metal with a continuous bead 6 around its edge,to strengthen it, and with a lateral flange 7 along one edge to whichone of the side edges of the fixed jaw is riveted. These side piecesform the means for securing the wringer to the tub and for this purposeare each provided with a recess having a wide portion 8 to receive thevertical wall a wooden pail and a narrow portion 9 to receive a likewall of a metallic pail. Owing to the provision of the wide and thenarrow portion 8 and 9 the device will swing outwardly when supported ona metallic pail if no means is provided to prevent this action, andtherefore I connect the side pieces 5 by a rod 10 the lowermost surfaceof which lies in a plane with the upper wall of the por; tion 9 so thatit may rest upon the upper edge of the pail and prevent the tilting.This rod also serves to tie the side pieces together.

The movable or swinging jaw is mounted between the side pieces andpreferably com prises two side members or arms 11 made of angled ironand connected by a pivot rod 12 which projects through perforations neartheir lower ends and forms a pivot for the jaw. Connecting the arms 11at their upper ends is a sheet metal plate rolled outwardly at 13 atit-s upper and lower edge, and stamped to provide vertical ribs 14 whichare `arranged to enter between the ribs 1 on the xed jaw, thedepressions between the ribs being provided with vertical slots or drainopenings 15 which are arranged opposite the drain openings 3 of thefixed jaw. I

To prevent a mop between the jaws dropping too low, I provide a stopplate 16 which is preferably carried by the fixed jaw and is formedfromthe same sheet of metal from which the latter is made, its free edgebeing rolled at 17 and transverse braces 18 being arranged at its ends,which are spaced from the side pieces 5 to permit the arms 11 to swing.By mounting the bott-om on the fixed jaw instead of on the movable jaw,I not only secure a strengthening of the fixed jaw but I secure aconstruction which requires less labor to operate it because the weightof the movable jaw is reduced.

The means for operating the swinging or movable jaw comprises preferablya'bent or curved lever 19 mounted to swing between the side pieces 5,and positioned nearer one of said pieces than the other, the lever forthis purpose having a yoke at its inner end composed of two arms 20 and21, the former being straight and the latter being substantiallyZ-shaped and both being connected at one end to the lever and at theother end to a pivot rod 22 secured at its ends in side pieces 5. Theyoke is connected to the swinging jaw by a U-shaped 'nember which hasits free ends bent outwardly at 23 to form pivotal connections with thearms of the yoke and has its horizontal portion 24 journaled on theswinging jaw, the metal lugs or strips 15a which are cut to form drainopenings 15, being alternately bent in opposite directions and wrappedabout said g @sof/1o portion 24 to provide the bearings, and the endlugs or strips serving to prevent sidewise movement of the U-shapedmember. lt will be noted that the arms 25 of the U- shaped member andthe lower portions of the arms of the yoke act as links and form a.toggle connection between the operating lever 19 and the side pieces 5.It will be further noted by reference to Fig. 2, that the pivot rod 22will be engaged by the links when the operating lever is thrown to openthe `iaws and will act as a stop to prevent the operating lever swingingto a position where the operator will be compelled to stoop to reach it.

Briefly stated, the operation is as follows; The device is fitted to thevertical wall of a pail so that the upper edge of the latter' will restwithin the recesses in the side frames and the mop is then placedbetween the jaws so that upon the movement of the operating lever toswing the movable `iaw the said mop will be compressed.

l claim as my invention.

l. In a mop wringer, a fixed jaw, a movable aw for cooperationtherewith, side pieces projecting from the fixed jaw, and each having arecess provided with a wide and a narrow portion to receive the walls ofpails of different thickness and a rod connect-ing said side pieces andpositioned to rest upon the upper edge of a pail positioned within thenarrow portions of the recesses.

2. ln a mop wringer, a fixed jaw, a movable aw for cooperationtherewith, side pieces project-ing from the fixed jaw and each having arecess provided with a wide and a narrow portion to receive the walls ofpails of different thickness, and a'device cooperating at a pointbetween the side pieces with the Lipper edge of a pail arranged withinthe narrow portions of the recesses.

3. In a mop wringer the combination with a fixed 'jaw and a movable awfor coperation therewith, of means for operating the movable jawcomprising a lever, a yoke having its arms branched from one end of thelever and pivotally mounted at their free ends in proximity to the outerface of the movable jaw, and a U-shaped member having its arms pivotallyconnected to t-he arms of the yoke above their ends and having itshorizontal portion pivotally connected to movable jaw.

4. In. a mop wringer, the combination with a fixed jaw, side piecesextending from the fixed jaw, and a movable jaw for cooperation with thefixed jaw, of means for operating the movable jaw comprising a lever, ayoke at one end of the lever, having a straight and a substantially Zshaped arm pivotally mounted at their free ends between their sidepieces, and the arms connecting` said arms above their pivotally mountedends to the movable jaw.

5. In a mop wringer, the combination with a fixed jaw, a pair of sidepieces extending 'from the fixed jaw, and a movable jaw for cooperationwith the fixed jaw, of means for operating the movable jaw comprising alever, links mounted between the side pieces and operated by the lever,and a U- shaped member having its arms pivotally connected to the linksand its horizontal portion pivotally connected to the movable jaw.

6. In a mop wringer, the combination with a fixed jaw and pair of sidepieces extending from the fixed jaw, of a movable jaw for cooperationwith the fixed jaw, straps struck up from the movable jaw to form drainopenings therein, a U-shaped member having its horizontal portion heldby the straps, links pivotally connected to the side pieces and to thearms of the U- shaped member, and a lever for operating the links.

7. In a mop wringer, a sheet met-al jaw provided with stamped verticalribs and a roll at its top, side pieces extending from the ends of thejaw, a bottom piece projecting from the lower edge of the fixed `jaw andspaced at its ents from the side pieces; a movable jaw comprising a pairof arms made of angle iron and pivotally connected to the side pieces,and a sheet of metal formed with vertical ribs and with a roll at itstop and its bottom; and means for operating the movable jaw.
